Abstract
A sheet handling apparatus includes a rotatable hollow sheet transport drum with a plurality of openings extending therethrough, a vacuum supply for supplying a partial vacuum to the interior of the drum, a drive for rotating the drum, and a stationary deflection plate disposed adjacent the outer drum surface. A vacuum shield is mounted within the drum and is movable from a first position, remote from the inner wall of the drum, to a second position, adjacent the wall. The shield, when in its second position, prevents the partial vacuum from being applied to the leading portion of a sheet on the drum so as to permit the leading edge of the sheet to deflect outwardly from the drum and strike the deflection plate.
